According to Cheryl Rosenfeld, an associate professor of biomedical sciences in the University of Missouri's Bond Life Science Center, loading up a bunch of California mice with a mega-dose of bisphenol A (BPA) showed researchers that "What we have observed in those models is that BPA affects male rodents differently from females."

So, humans are expected to demand that BPA be banned based on the behavior of BPA-besotted California mice, but not the deer mice on which previous similar research was conducted. As noted in the release, "The two rodent species have contrasting mating behaviors." That's right, it depends on the sexual proclivities of the species of the mice involved and one has to make a mighty leap of faith that Ms. Rosenfeld's research applies to humans.

Rosenfeld's earlier work received notice in a January 2, 2013 Science Daily article which pointed out that, "Following a three-year study using more than 2,800 mice, a University of Missouri researcher was not able to replicate a series of previous studies by another research group investigating the controversial chemical BPA."

A synopsis of the earlier study noted that "Rosenfeld's group extended the studies to include animal numbers that surpassed the prior studies to verify their findings were not a fluke and to provide sufficient numbers of animals to ensure that significant differences would be detected if they existed. However, even these additional numbers of animals and extended experiments failed to reproduce the earlier findings."

It's worth noting that Ms. Rosenfeld's later research involving monogamous California mice represented a dose that is a 1,000 times greater than a human would ingest. This research suggests that the anticipated outcome would demonstrate that BPA is harmful.

It reflects a global propaganda campaign to ban a chemical that has been safely in use for fifty years. This campaign is the subject of my six-part series on BPA that can be found at http://thebpafile.blogspot.com/, a blog I maintain that includes other articles on the subject.

As noted on The BPA File, "In 2011, 'the German Society of Toxicology released a review of more than five thousand previous studies of PBA exposure that concluded that BPA exposure represents no noteworthy risk to the health of the human population, including newborns and babies. Researchers concluded that BPA is neither mutagenic nor likely to be a carcinogen."

Five thousand studies! At what point does 50 years of safe use to coat the insides of aluminum food cans, protecting the contents against food pathogens such as botulism, put this campaign by environmental groups and others to rest? How many more studies do we need to demonstrate the safety of BPA in making shatterproof safety goggles, DVDs, and scores of other products we use every day?

In March 2012 an Associated Press health reporter, Matthew Perrone, reported that "The Food and Drug Administration has rejected a petition from environmentalists (the Natural Resources Defense Council) that would have banned the plastic-hardening chemical bisphenal-A from all food and drink packaging, including plastic bottles and canned food." The petition was rejected because the "petitioners did not present compelling scientific evidence to justify new restrictions..."

How compelling is yet another study that involved feeding California mice 1,000 times more BPA than humans would ever ingest? And how would any rational person conclude that alleged changes in monogamous California mice – but not the polygamous deer mice – could be extrapolated to suggest that humans would be affected?

An August 8, 2011 editorial in The Wall Street Journal, "Postscript to a Panic," noted a study, "financed by the EPA...involved feeding (human) subjects a BPA-rich diet for 24 hours. Researchers then monitored their blood and urine for traces of the chemical" only to find that "the result was BPA levels too low to detect."

The sheer absurdity of the campaign to get BPA banned reflects a deeper, more sinister agenda by environmental organizations like the Natural Resources Defense Council. It is the belief that the Earth's human population must be reduced to protect it. Banning BPA would put millions at risk of death from food-borne diseases like botulism.

Given the tenacity with which such groups prosecute their agendas, we can be assured that these obsessed anti-BPA "researchers" aren't going to go away.
